About the Image Resizer
This image resizer lets you change the dimensions of any picture without installing software. Set an exact width and height, or scale by a percentage, and download the result.
Lock the aspect ratio to avoid stretching, or unlock it to fit an exact size. You can also choose the output format, so the same tool doubles as a quick converter.
Everything happens in your browser using the Canvas API, so your image is never uploaded to a server.

Frequently asked questions
- Will resizing reduce the quality?
- Making an image smaller keeps it sharp. Enlarging beyond the original size can look soft, because the browser has to invent extra pixels.
- Does it keep transparency?
- Yes, if you export as PNG or WebP. Exporting as JPG removes transparency and fills it with white, since JPG has no alpha channel.
- Is my image uploaded anywhere?
- No. The image is resized locally in your browser and never leaves your device.
